Flavonoids: chemistry, biochemistry, and applications

by:  Øyvind M. Andersen, Kenneth R. Markham

Book Description :

We considered this volume timely in that the last book of this general type, TheFlavonoids — Advances in Research Since 1986 (edited by Jeffrey B.  Harborne), appeared over a decade ago. Since then, advances in the flavonoid field have been nothing short of spectacular. These advances are particularly evident in the contributed chapters that cover: the discovery of a variety of new flavonoids; the application of advanced analytical techniques; genetic manipulation of the flavonoid pathway; improved understanding of flavonoid structures and physiological functions in plants and animals; and, perhaps most importantly,the significance of flavonoids to human health.

Anthocyanins: Biosynthesis, Functions, and Applications

By Kevin Gould, Kevin Davies, Chris Winefield

  • Publisher: Springer
  • Number Of Pages: 330
  • Publication Date: 2008-10-08
  • ISBN-10 / ASIN: 0387773347
  • ISBN-13 / EAN: 9780387773346
  • Binding: Hardcover

Product Description:

In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops.

Chemistry and Biology of Ellagitannins: An Underestimated Class of Bioactive Plant Polyphenois

by:  Stephane Quideau

Book Description :

This book is the first of its kind that focuses on the chemistry and biology of ellagitannins, a special class of naturally occurring polyphenols which have so far not received the attention they deserve. These polyphenolic substances are found in many plants, including numerous food sources. They not only exhibit unique structural features that fascinate most chemists who are aware of their existence, but also express remarkable biological activities that have yet to attract the interest of the pharmaceutical industry. This is surprising because ellagitannins have been identified as active principles in traditional Chinese medicines. The principal aim of this book is to set the record straight.

Advances in Plant Glycosides, Chemistry and Biology (Studies in Plant Science, Volume 6)

by: Chong-Ren Yang, Osamu Tanaka

  • Publisher: Elsevier Science Pub Co
  • Number Of Pages: 458
  • Publication Date: 1999-02-01
  • Sales Rank: 5535681
  • ISBN / ASIN: 0444501800
  • EAN: 9780444501806
  • Binding: Hardcover
  • Manufacturer: Elsevier Science Pub Co
  • Studio: Elsevier Science Pub Co

Book Description:

In the plant kingdom a variety of chemical constituents occur in a glycoside form (conjugation with sugar). Glycosides are important, secondary metabolites. The structural diversity is a result of the vast amount of varieties and stereochemical configurations of the sugar component. Aglycones belong to terpenoid, steroid, flavonoid, quinonoid, lignan, other simple phenolics, and isothiocyanate. However, biological activities of glycosides are, in many cases, susceptible to the nature of sugar moieties, even though their aglycone is the same.

Since the 80s, plant glycosides have been attracting an increasing volume of interest from botanists and phytochemists world-wide for the following reasons:

• They are difficult to isolate and purify

• They have a very important biological function in plant life and remarkable biological activities

• They are a very important resource of natural medicine, health food, cosmetics and food

Synthesis and Characterization of Glycosides

By : Marco Brito-Arias

  • Publisher: Springer
  • Number Of Pages: 352
  • Publication Date: 2006-12-12
  • Sales Rank: 2575409
  • ISBN / ASIN: 0387262512
  • EAN: 9780387262512
  • Binding: Hardcover
  • Manufacturer: Springer

Book Description:

This textbook discusses glycosides, which is an important area of sugar chemistry. Arias describes the general procedures commonly used for preparing a wide range of O-N- and C-glycosides, focusing on the preparation of the main glycosyl donors, and the coupling reaction conditions needed for the glycoside bond formation. Since characterization is also a very important topic to be treated, there is an introductory analysis about NMR spectroscopy, X-Ray diffraction and mass spectra of glycosides.
